SAMUEL W. TAYLOR, or BALTIMORE, MARYLAND. i ADJUSTABLE Ec'oi'ziu'rmc.

Be it known that I, SAMUEL W. TAYLOR,- a 0 1l31Z 6n of the United States, residing at Balt1more,-in the State of Maryland, have inin Adjustable Eccentrics of which the follow- I to aneccentric for the driving-axles of locomotives. These eccentrics serve to operate the steam-valves.

The object of this invention is to provide This invention relates The invention isillustrated in the accompanying drawings, in which Figure 1 is a view of the axle and eccentric. Fig. 2 is a side view of the eccentric, the axle being in cross-section. Figs. 3,4, and 5 are views of the small section or clamp part of the eccentric. Fig. 6 is a view separately of one of the two keys that are used to hold together the two parts or two sections of the eccentric. Fig. 7 is a viewseparately .of the Fig. 8 is a sectional view of the eccentric mounted on the axle,taken on the line The letter a designates the driving-axle of a locomotive, which is provided with two stout b in line with each other, but spaced apart to admit clamping the eccentr1c'between them. I The eccentric, as usual, is made of two sections .0 c. The 'smallersection c has two pins a, each having a'slot e, and when the two sections are together keys f, entered in the saidslots e, will hold the tWo sections space on the axle between the twolugs.

The large section chas a segment-shape space or opening g, into which the pins d project. (See Fi 2.) It also has a half-hub h, which snugy takes between the two lugs b on the axle. These two axlelugs serve two purposes-first, to prevent the eccentric from shifting longitudinally on the axle a; sechas a lateral flange j at each side. The outer inner side next to the axle has a V-notch k, which takes over one of the lugs 11 on the axle. Both flanges j are alike. Each flange f has two set-screws i pitched in opposite directions, and the ends of. thescrews impinge Specification-of Letters Patent. 7 Application filed July 20, 1905. Serial No. 270,494.

' Patented. March 13, 1906.

It will be seen that by loosening one set- I screw "t on each flange and tightening-the htly turning While the eccentric has been describedwith special reference to a locomotive-axle,

it is obvious it is applicable to other uses where shafts are used. v

The lugs rigid on the axleconstitute one form ofmeans'which may be used for the ends of theset-scr'ews to impinge against.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent; is

1. The combination of an axle provided with two lugs separated by a space an eccentric on the axle and snugly fitted in the space between the ,two lugs, there being a lateral other set-screws the eccentric may be slightly each flange flange at the side of the eccentric said flange projecting over one of the said lugs, and

posite directions, the ends of the screws two set-screws in said flange and pitched in oplmpinging' against opposite sides of the lug, I

as and for the purpose set forth..

2. The combination of an axle; an eccentric on the axle and provided at each side with a laterally-projecting flange; two setscrews in each of said flanges and pitched or inclined in op osite directions, and means rigid on the axl a and covered by said projecting flanges andagainst which the ends of said set-screws impinge.

3. The combination of tric on'the axle, two set-screws on the eccenan axle; an eccen-.

trio and pitched or inclined inopposite directions and means rigid on the axle against'opposite sides of which the ends'of said oppositely-pitched set-screws im inge.

In testimony whereof I a my signature in presence of two Witnesses.
